Remarks
All interfaces are enabled by default as shipped from the factory.
If you disable the LAN interface, all associated LAN services will not be
started when you power on the instrument.
The 34410A/11A/L4411A uses the following LAN ports:
Port 5024 is used for SCPI Telnet sessions.
Port 5025 is used for SCPI Socket sessions.
The interface setting is stored in non-volatile memory, and does not
change when power has been off, after a Factory Reset (*RST command),
or after an Instrument Preset (SYSTem:PRESet command).
